Masteron is a steroid highly valued by competing bodybuilders. The great popularity of this injectable steroid in bodybuilder circles is due to the extraordinary characteristics of its included substance. Drostanolone propionate is a synthetic derivative of dihydrotestosterone. This causes the Masteron not to aromatize in any dosage and thus, it cannot be converted into estrogens. This distinctive feature is confirmed by the Belgian manufacturer, Sarva Syntex, who on the enclosed package insert calls Masteron a steroid with strong, antiestrogenic characteristics. Since Masteron is a predominantly androgenic steroid, the athlete can increase his androgen level without also risking an increase in his estrogen level.

This results in a dramatically improved hardness and sharpness of the muscles. One must, however, make a distinction here since Masteron does not automatically improve the quality of muscles in everyone. A prerequisite is that the athlete's fat content must already be very low. In this case Masteron can then be the decisive factor between a smooth, flat muscle or a hard and ripped look. For this purpose Masteron is often only used during the last four weeks before a competition so that the muscles get the last "kick." Masteron is especially effective in combination with steroids such as Winstrol, Parabolan, Primobolan, Oxandrolone and also Testosterone propionate. The usual dosage taken by athletes is around 100 mg three times per week. Since the substance drostanolone propionate is quickly broken down in the body, frequent and regular injections are necessary. This fact makes Masteron a very interesting steroid when doping tests must be passed by a negative urine analysis. Since the propionate substance of drostanolone does not remain in the body very long in a sufficient, detectable amount, athletes inject the compound with great success up to two weeks before a test. However, since it also has anabolic characteristics and thus helps the build up of a high-qualitative muscle system, the use of Masteron is not only limited to the preparation stage for a competition. Athletes who want to avoid water retention and who readily have a problem with an elevated estrogen level, likewise appreciate Masteron. Also in this case usually one ampule (100 mg) is injected every second day. In combination with Primobolan, Winstrol or Testosterone propionate no enormous strength and weight gains can be obtained, only high-quality and long-lasting results. Although women do not use Masteron very often some national and international competing female athletes do take it before a championship.

The dosages observed are normally 100 mg every 4-5 days. Masteron is not hepatoxic so liver damage is quite unlikely. High blood pressure and gynecomastia are not a problem since neither water nor salt retention occurs and the estrogen level remains low. The main problem are acne and a possible accelerated hair loss since dihydrotestosterone is highly affinitive to the skin's androgen receptors, in particular, to those on the scalp. Since Masteron. in most cases, is not administered in excessively high dosages and the intake, at the same time, is limited to a few weeks, the compatibility for the athlete is usually very good.
